MACHINE FOR RECOVERING on. FROM WASTE.

SPECIFICATION forming part of Letters Patent No. 655,683, dated August 14, 1900.

Application filed August 17,-1899. Serial No. 727,580. (No model.)

T0 ail whom it may concern.-

Be it known that I, JOHN B. BENTON, a citizen of the United States, residing at Elizabetli, Union county, in the State of New Jer- Improvement in Apparatus for Recovering Oil from Waste, of which the following is a specification.

My apparatus is adapted to treat cotton waste, such as'is commonly used in wiping the oily surfaces of machinery, to powerfully express the oil, allowing the fiber and the oil to be reused for the same or for other purposes many times. As a rule the clean waste should be used with clean oil, and it naturally results that the waste becomes darker in color and contains a larger proportion of particles of metal and of other foreign matter, and the oil is correspondingly deteriorated as the waste and the oil are successively reused.

My improved apparatus comprises a simple bed-plate stiffly secured on a'firm foundation and adapted to catch the oil and lead it away. The expressing is effected by vertical rolls operated by hand, between which the waste is slowly passed, the compression being also effected and controlled by efficient means operated at will as the work proceeds.

- The apparatus is of little bulk or cost and is eminently convenient for large or small users of machinery.

I feed the waste in at a predetermined height on the upright rolls by the aid of a feed-platform matched close to the receiving side of oneroll, which turns on a fixed axis and as nearly as practicable to the other roll, which latter is on an axis which shifts its position laterally. The waste emerges at nearly the same level as it enters and is received on a delivery-platform set sufficiently low to allow for the waste spreading and sinking a little lower.

The accompanying drawings form a part of this specification and represent what I consider the best means of carrying out the in- 'vention.

Figure 1 is a perspective, Fig. 2 a front elevation, and Fig. 3 a plan view, of the entire apparatus. Fig. 4 is a side elevation of the apparatus.

Similar letters of reference indicate corresponding parts in all the figures where they appear.

A is a bed strongly secured upon a foun 'dation B bymeans of stout bolts. sey, have invented a certain new and useful G is a roll-free to turn on the post D and provided with a gear-wheel G and a stout ratchet-wheel G I is a hand-lever arranged to turn horizontally on the same bolt or post D, having a pawl J turning on a pivot I and subject to the influence of a gentle spring K, which takes hold of a pin I on the lever I and a pin J on the pawl J and reliably engages the ratchet. By strongly vibrating this lever the roll G is turned step by step.

M is a corresponding roll which acts in concert with the roll G to strongly compress the waste as it is passed through between. This roll M is centered on an upright bar N, which is connected by links 0 to the rear post E and is free to move to and from the roll G by the lateral swinging of these links.

P is a rocking piece loosely turning on the post F and controlled by the handle P inserted in the stout lug P. Two lugs or short arms P P on the opposite side carry an upright bolt P, which by horizontal links Q engage with the axial bar N, before referred to. The parts are so proportioned that theoperator pulling the handle P with varying force can act powerfully togglewise through the short arms P P and the links Q to urge the rolls strongly. By relaxing the pull on the handle P he can allow them to yield apart.

The bridge A supports at the points represented two short vertical pins R S, which form centers for loose gear-wheels T U. The gear-wheel G on the roll G engages with and gives motion to the gear-wheel T; This engages with the gear-wheel U, and the latter with the gear-wheel M on the movable roll.

M. The roll M may move toward. and from the roll G without appreciably disturbing the relations of these gears. The gear insures that the rolls turn equally and in the proper direction at each of the series of strong forward movements imparted by the right hand of the operator through the lever I. It will be understood that the rolls being turned step bystep by the lever I and its connections, while the other hand controls the handle P which by the links Q urges the roll M toward the roll G with a force which is graduated at will, may instantly and conveniently allow for great variations in the thickness of the mass of waste being passed through. The oily waste being treated is fed forward on an elevated platform W. After the oil has been expressed the nearly-dry waste is received on a lower platform X, sufficiently high to be out of the oil. The cleansed waste will be pushed from this latter platform and allowed to fall into a receptacle, where it is preserved for reuse.

The platforms W and X are made separate from the bed and held up by descending flanges. The edges which are presented toward the rolls match closely to the roll G and as closely as may be to the roll M, while allowing for changing the position of the latter as it swings horizontally on the links Q. I have in my experiments made the receiving-platform X perforated; but this is not essential. The oil expressed flows down on the rolls and none in ordinary working touches the platform.

Modifications may be made in the length and in the proportions of the parts without departing from the principle or sacrificing the advantages of the invention. The wheels G and G may be cast integral with each other and with the roll G; but I prefer to form and finish them separately and firmly attach by screws. In many cases the waste may be steamed or otherwise treated and the operation of expressing the liquid partially saturating the fiber repeated with advantage.

I claim as my invention- 1. In apparatus for removing oil from fibrous waste, the combination with a bed provided with a rim and drain, of a pair of vertical expressing-rolls, means for rotating the same located at one side, and feed and receiving platforms both above the bottom of the bed within the rim area thereof, the receiving-platform being in a lower plane than that of the feed-platform, and means located at the opposite side for varying the position of one roll relative to that of the other Without interrupting the mesh substantially as herein specified.

2. In apparatus for removing oil from fibrous waste, the combination of a Vertical roll having a gear-wheel and mechanism for positively turning it located at one side, a vertical roll M supported in movable bearings and also having a gear-wheel, intermediate gearing for transmitting motion from one roll to the other, and hand mechanism located at the opposite side for shifting the bearings of the roll M to and from the roll G, the mesh of the gear of the former roll with the intermediate gearing being maintained, substantially as herein specified.

3. In apparatus for removing oil from fibrous waste, the combination with a bed provided with a rim and drain, of a pair of vertical expressing rolls geared together, hand mechanism for positively turning one of said rolls, a toggle-bearing and hand provision for shifting the other roll Without disturbing its mesh, and feed and receiving platforms within the rim area thereof, the receiving-platformbeingin alower plane than that of the feed-platform, substantially as herein specified.

4. In apparatus for nemoving oil from fibrous waste, the combination with a pair of vertical expressing-rolls geared together through intermediate gearing, of a reciprocative hand-lever having a .pawl engaging the gear of one of said rolls to turn the same, links 0, O, in which the other roll bears to permit its movement relative to the fixed roll without disturbing the mesh with the intermediate gearing, hand provisions connected with said links for so shifting the other roll, feed-platform, a lower receivingplatform, and a bed provided with a rim and drain, substantially as herein specified.

5. In apparatus for" removing oil from fibrous waste, the combination with a base having a suitable oil-receptacle, a bridge A a fixed roll bearing in the base and bridge and having a gear-wheel meshing with intermediate gearing also journaled in the bridge, hand provisions for actuating the gear-wheel of said fixed roll, pivoted. links 0, O, carrying a roller M having a gear-wheel meshing with the intermediate gearing, and a handoperated piece P connected to the link-bearings of the roll M to move the same and said roll to and from the fixed roll, substantially as herein specified.

6. In apparatus for removing oil from fibrous waste, the combination with a base having a rim and a drain for retaining and conveying away the oil, of a vertical roll on a fixed center, a hand-operated lever carrying a spring-pawl for engaging and rotating the same, a vertical movable roll, link connections and gearing for transmitting motion to the same from the fixed roll, and hand controlling means for shifting the other roll at will during the operation, substantially as herein specified.

In testimony that I claim the invention above set forth I affix my signature in presence of two witnesses.
